In March 2007 Lowell Darling met Amela Vucina, a pianist from Bosnia who had fled the war in 1993 and settled in Berlin.

Soon afterwards, Amela was forced by the German governement to leave the country. Having lost everything in the war, she had nowhere to return to. Amela and Lowell decided to turn the journey into several quests. For one, to find a site to start Lowell Darling's Unborn Soldier Project, an art installation. Nexct, the idea was to find, then then to play, all the pianos Amela could find between Split and Mostar. Lastly, they sought to find Amela's former piano teacher, whom she hadn't seen since she left Mostar.

Lowell documented the whole trip with his newly acquired camera and later back in Berlin, Lowell gave the footage to Berlin artist Julian Ronnefeldt who then worked his way through 48 hours of footage to compose the documentary All the Pianos in Mostar.
